DYNAMIC SUPPORT DEVICE FOR KEYBOARDS A keyboard, forearm, wrist and hand support device for use in conjunction with the keyboard of a video display terminal work station. The support device is adapted to reduce occurrences of repetitive strain injury by reducing stress on the user's shoulders, arms, wrists and hands. The support device comprises an elongate guide track and a pair of support assemblies which are adapted to support a user's forearms, wrists and hands thereon. Each of the support assemblies comprises a carriage member slidably engaged to the guide track and a linkage member pivotally connected to the carriage member. Pivotally connected to the linkage member is a support member which is sized and configured to support the user's forearm and wrist and the palmar surface of the user's hand. The pivotal connection of the carriage and support members to the linkage member and the slidable engagement of the carriage member to the guide track facilitates dynamic lateral and longitudinal movement of the support member and hence the user's hands relative the guide track.
